24" iMac screen flickering

Ive had my imac for about 6 months now and have had no problems with it. Then yesterday the screen flickered around the edges and in the lower middle of the screen. One day later, it is almost constant and very hard on the eyes. Should I take it back to the store and get it fixed/replaced? Has this also happened to you?

Hasn't happened to me, but if it's still under warranty, I definitely would try seeing if they can fix it.

Get it back to Apply, they have got to sort that out for you.
